Changes 1.8.8:
Fixed incorrect unique_together field name generation by inspectdb.
Corrected __len query lookup on ArrayField for empty arrays.
Restored the ability to use custom formats from formats.py with \ 
django.utils.formats.get_format() and the date template filter.
Fixed a state bug when migrating a SeparateDatabaseAndState operation backwards.
Fixed missing varchar/text_pattern_ops index on CharField and TextField \ 
respectively when using AlterField on PostgreSQL.
Fixed a state bug when using an AlterModelManagers operation.
Fixed a regression which prevented using a language not in Django’s default \ 
language list (LANGUAGES).
django.views.decorators.cache.never_cache() now sends more persuasive headers \ 
(added no-cache, no-store, must-revalidate to Cache-Control) to better prevent \ 
caching. This fixes a problem where a page refresh in Firefox cleared the \ 
selected entries in the admin’s filter_horizontal and filter_vertical \ 
widgets, which could result in inadvertent data loss if a user didn’t \ 
notice that and then submitted the form.
Fixed a regression in the admin which ignored line breaks in read-only fields \ 
instead of converting them to <br>.
Made loaddata skip disabling and enabling database constraints when it \ 
doesn’t load any fixtures.
Fixed a crash in QuerySet.values()/values_list() after an annotate() and \ 
order_by() when values()/values_list() includes a field not in the order_by()
